Heavy rain and thunderstorms have battered much of the country as Metservice warns some areas may still experience flooding.
The forecaster also issued several severe weather warnings. The North Island will bear the brunt of the bad weather with an orange heavy rain warning in place for Northland and the Coromandel Peninsula.
The areas should expect thunderstorms on Monday and potential flooding as the rain causes streams and rivers to rise rapidly.
Auckland is also being battered with a heavy rain watch in place for the city, including Great Barrier Island.
A severe thunderstorm watch is also in place for Northland, Auckland, Great Barrier Island, Coromandel Peninsula, and the Waikato.
In a warning on Monday afternoon, Waka Kotahi urged motorists to take care when travelling through the Karangahake Gorge after Coromandel was battered with heavy rain.
"Due to excess surface water through the Karangahake Gorge, caution is advised along this route," Waka Kotahi said in a tweet.
"Flooding, falling trees or slips are possible. Please be prepared for hazardous driving conditions: slow down, increase your following distance and keep your lights on."
